摘要: 通过对稻属(Oryza L.)及其近缘属等18 个禾本科植物单拷贝核基因TPI 序列进行扩增和测序,分析其系统进化关系及序列差异,并设计鉴定疣粒野生稻(O. granulata)特异的分子标记。序列分析表明,栽培稻间TPI 基因序列碱基变异少,野生稻相对变异丰富,其中疣粒野生稻变异尤为明显,根据疣粒野生稻的TPI 基因序列特异位点设计引物,利用这一分子标记对疣粒野生稻进行准确鉴定。

Abstract: In this paper, single-copy nuclear TPI genes of Oryza L. and its related genera were amplified and sequenced, we analyzedtheir phylogenetic relationships and sequence differences, designed specific primers for Oryza granulata. Sequences analysis indicate thatthere were few variations between cultivar rice, but many variations between wild rice species, especially sharp variations were found for Oryzagranulata. On the basis of these variations, we designed Oryza granulata specified primers for species identification.
